Results of studying effect of mineral fertilizers in combination with inoculation with nitrogen-fixingbacteria on chickpea productivity in podzolic black soil of Right-Bank Forest-Steppe of Ukraine havebeen shown. Pre-sowing bacterization contributed to the active formation and functioning of thesymbiosis, provided that the background of nitrogen fertilizers did not exceed 60 kg/ha. Under theinfluence of mineral fertilizers both separately and in combination with seed inoculation, chickpea yieldincreased by 10.8–15.2 hwt/ha compared to the variant without fertilizers and without inoculation.It was established that in order to obtain high and stable yields of chickpea seed in podzolic blacksoil of Right-Bank Forest-Steppe of Ukraine with low content of nitrogen of alkalihydrolyzing compoundsand high content of mobile phosphorus and potassium, its fertilization system should include applicationof phosphate and potash fertilizers in the dose of 60 kg/ha during primary tillage, and nitrogen fertilizers– for presowing cultivation. Before sowing, seeds should be processed with the suspension of ammoniummolybdate and Ryzobofit.
